INFOID:0000000010054754

Regarding Wiring Diagram information, refer to 

MWI-87, "Wiring Diagram"

.

1.

CHECK FUSES

Check for blown combination meter fuses.

Is the inspection result normal?

YES

>> GO TO 2

NO

>> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.

2.

POWER SUPPLY CIRCUIT CHECK

1. Disconnect combination meter connector.

2. Check voltage between combination meter harness connector

M24 terminals 1, 2, and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> Check harness for open between combination meter and fuse.

3.

GROUND CIRCUIT CHECK

1. Turn ignition switch OFF.

2. Check continuity between combination meter harness connector

terminals 3, 4, 23 and ground.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Repair or replace harness or connector.
